Solvation dynamics of 4-aminophthalimide in water-in-oil microemulsion of Triton X-100 in mixed solvents
Article Abstract:
Picosecond time-resolved Stokes shift is used in studying solvation of 4-aminophthalimide (4-AP) in water-in-oil microemulsion of Triton X-100 in mixed solvents with 30% benzene and 70% n-hexane. Triton is a neutral surfactant which does not use sodium ions in the solvation of microemulsions. Results show the steady-state spectrum of 4-AP in microemulsion is very different from that in TX reverse micelle or in water. This suggests that 4-AP molecules stay in the water pool and the micropolarity of the water pool is different from ordinary water.

Direct observation of essential DNA dynamics: melting and reformation of the DNA minor groove
Article Abstract:
Time-resolved emission spectra (TRES) of the fluorescent probe H258 is used for characterizing the synthesized dodecamer and a genomic DNA environment at different temperatures along their melting pathway. The results have shown that the dynamics of the environment has included a vital contribution from bound water molecules and cations present in the minor groove of the native DNA.
